72 CB350 build - First build - spring deadline

Looking forward to this winter project. Also looking forward to some help from you guys since this is my first build. The bike is a 72 CB350 that I got from a friend. I had been looking at some of these great builds on the site and thought it would be a great winter project. I'm in Michigan, so winters can be loooong! I remembered my buddy had one of these a few years back. I gave him a call and said I was looking at building a cafe and he said that's sound kick ass! 2 days later he road the bike over and we carried it down to my basement. Hopefully I can get it out when I am done!

The bike hadn't been started in 9 years. It fired right up! He did an oil change just to make sure everything was good for the ride over.

Over the weekend I tore it all down to the frame. Labeled all bolts and put them in plastic baggies.

Plans are to slim it down from items I won't need, give it some fresh paint and replace some parts along the way. I also plan on rebuilding engine, forks, brakes, etc..

Enough with the talk. I'm sure you guys want to see some pics. First pic is when I got it. The next pics are in the process of tear down. I'm not sure what I'm going to do next.

Easy welcome to the site. You have a good start on the bike already. Do you have any thoughts in your head as to where you wanna go with the build. Looks like detabbing is the next step. Keep us informed and welcome to DTT.
 
Yes, definitely detabbing is the next step. I need to figure out what I want/need to take off. I will probably go more of brat style with the bike. Put some drag bars on it with somewhat of a flat seat that slopes up in the back. I'm sure I will change my mind a few times in the process. I found access to a sand blaster today. I will need to make a soda blaster for the engine and carbs though.
 
I was talking to my uncle yesterday about my project. He says, "I think I have one of those bikes out at the farm in the back barn". He told me that I could have the bike if I wanted. I went out to check and see what it was like. Turns out it was a Honda 300 from the 60's. it didn't have an engine in it and was a little rough from sitting. I was able to get the tank off of it. It's a pretty cool tank. No dents! Just have to clean it up a bit. Should look pretty nice on the 350.

terrible looking tank. I am prepared to save you from any further shame and humiliation by allowing you to send it to me.

I have had an built so many CB77's that if it were me, I'd be looking for a motor to fit that bike and build a nice sixties special out of it. The old 305 had better brakes at both ends, looked better and ran like a charm. Does he still have the motor lying around somewhere? and a title hiding in an old kitchen drawer?

Do the 350 as a first build and learn from that and do the CB77 next as a keeper - assuming you have titles for both of course.
 
Hmmm. Teazer, not sure how to take that comment. Do you really think it will look terrible or are you just saying that to get me to send it to you?

The engine was not laying around the bike and we have no idea where the title would be. The barn is huge with different levels. May have to go back out when there is better light and warmer to look around.
 
Sandblasted some parts today. Prepping for powder coat. Need to start detabbing the frame. Not sure where to start. Probably just do all the seat brackets and side cover tabs. Also will get rid of the center stand brackets.

Also started to sand the front forks in prep for polishing. This sucks! Got one of them done. Did 220, 400, 600 then 800. From what I have read this is the way to do it. Is there any better/easier way? Hopefully after the polish they will look better than it does now.

Oh yeah! Also ordered a soda blaster from harbor freight. It was a cheap one but a few guys said they work pretty good. Going to do the engine, carbs and hubs as soon as it comes in.

Nice. Is soda blasting the same as sand blasting with an air compressor, just switching out the media? I've seen those dedicated soda blasting tanks at hf. Would like to soda blast someday, but hope my options aren't the later.
 
Same technique as sand blasting but a bit less abrasive. I got this one...

It is a cheap one, but didn't really want to spend a ton. A few guys on DTT said it worked pretty well. Will need to probably fill up the hopper fairly often, but I don't have a lot to do.
 
Got a little done tonight. Some detabbing and chopping the back off. Still need to do some grinding and smoothing. Also going to try and use the hoop from the center stand as my rear hoop for the seat. Not sure if this is going to work, but we'll see. There is a lot to remove from it and may be more of a pain in the ass.

Ordered a bench polisher/buffer the other day! Got this in the mail today. Looking forward to this weekend to give it a try!

I was able to use the soda blaster last week. Unfortunately all I have is a pancake compressor. It definitely is not enough air to use this properly. Here is a pic of the carbs. They were not in bad shape to begin with. The PO painted them. The soda blaster had no problem taking the paint off. It would have been a much easier project with a bigger compressor. The carb on the left was done. You can see the chrome cap is a bit cleaner.

Tore down the rear wheel. Was going to get new spokes, but these were not in to bad of shape. I cleaned every one of them. I'm probably going to paint them. I'm struggling with what to paint. Originally thought I would just polish the hubs and keep the chrome rims. Either I don't have the patients or the skills to properly polish something. I can't get the hubs or forks to shine like some of the guys on the site. I'm okay with them not being as shiny as chrome. I have access to an e-coat system. Only $5 per hanger. Pretty cheap! Thinking I may just coat the hubs and rims. The rims have a bit of rust that I can't get out.

I hit it with 220, 400, 600, 800 then the polishing wheel. Having a heck of a time getting in the fins of the hub.
 
Why are you rebuilding the motor??

Looks pretty good in the pics....not leaking. Were you able to check the compression, when it was running??
I wouldnt rebuild it, unless its a last resort.......these are pretty bullet proof motors.
